UPPER AND LOWER PLATE FOR FIRE-BOWLS.

SPECIFICATION foIming part of Letters Patent No. 379,594, dated March20, 1888.

Application filed March 28. 1887. Serial No. 232,808.

To all whom it may concern:

Be it known that I, ALBERT S. NEWBY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Upper and LowerPlates for Fll6-BOWlS; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in the lower fire-bowls forstoves; and the ob jects of the invention are to provide upper and lowerplates for the fire-bowl, with a series of circular grooves ordepressions on the faces of said plates adjacent to the edges of thebowl, whereby one or more of the series of rings formed by said groovesor depres sions may be removed by breaking either from the outside orinside of said plates, thereby preparing the plate, when occasiondemands, for use upon any-sized lire-bowl.

The invention consists, primarily, in a plate having a series of groovesor depressions on its face, and means for its attachment, as will bemore fully described.

The invention further consists in the features of construction andcombinations of parts, as will be hereinafter more fully explained andclaimed.

In the drawings, Figure 1 is a perspective view of a fire-bowl having myimprovements applied. Fig. 2 is a detail view of the top plate.

Corresponding parts in the figures are denoted by the same letters ofreference.

Referring to the drawings, Av represents the lire-bowl, which, as shown,is flaring, so that the coal will be fed to the bottom thereof, and willnot lodge or hang to the sides of the bowl.

B represents the bot-tom plate for supporting the lower end of the firebowl, and to which the stationary grate is attached. This plate iscircular in form, and is provided with a central opening of sufficientsize to admit the stationary grate O. The said plate is formed on itsupper and lower sides or faces with a series of circular rings ordepressions, on any one of which the lower edge of the firebowl isadapted to rest, and is provided with inwardly-projecting lugs, to whichthe stationary grate is bolted or otherwise firmly secured.

(No model.)

The movable grate D fits in a central opening in the stationary grate,and is adapted to be shaken and overturned, as usual. It is preferableto so arrange the shaking-grate that its load will be discharged towardthe rear instead of the front end of the stove, so that all possibilityof live coals or ashes falling on the floor of the room in which thestove is lo cated is avoided.

E represents the upper plate, which is provided on its upper face, ashort distance from its inner edge, with a circular groove ordepression, c, and between said groove 0 and said outer edge, on bothits upper and lower faces, with a series of depressious,f. On its underface, near its inner edge, said plate is provided with a groove, 9, asshown. On the upper face of said plate, between the groove 0 and theinner edge of the plate, are provided a series of depressions, h. WVheuthe fire-bowl is a large one, it fits in the groove 6, and that portionof the plate between the groove 6 and the inner edge is broken off. hena smaller bowl is employed, the plate is reversed or inverted, and thatportion be tween the groove 6 and the outer edge of the plate is brokenoff. The said plate is provided with holes or openings which are adaptedto receive bolts 1', passing through lugs j, formed on the upper edge ofthe fire-bowl, for securing the bowl and plate together.

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described fire-bowl plate,cousisting, essentially, of anannular plate provided with breaking grooves near its inner and outeredges, whereby it may be increased in size interiorly and decreased insize exteriorly to suit stove-bodies of different sizes, substantiallyas set forth.

2. The hereiudescribed fire'bowl plate,provided with seats for the endof the fire-bowl, arranged alternately on the under and upper sides ofthe plate, and having breaking grooves near its inner and outer edges,whereby the plates may be fitted to stoves of different sizes,substantially as set forth.

In testimony whereof I have affixed my sig nature in presence of twowitnesses.

ALBERT S. NEWBY.
